Hello everybody, If anyone can help me in the following it would be great. In the simulink window, I have a power system designed with wind turbines in it. I'm supposed to study the harmonic analysis on it using FFT from the powergui environment block. I measured the voltage and the current output of the wind turbine which is supposed to have a huge amount of harmonic contents. My problem is, whenever I change the start time of the FFT window, the THD (Total harmonic distortion factor) changes. So anyone has an idea what is the suitable time to obtain correct THD, or even how should I select this time??? Any ideas…?!!
